Your cart is empty.Straight shank, CNC precision cam ground, M35 cobalt, chatter-free cutting action. Made in Great Britain. Cobalt steel tools are similar to high-speed steel, but with more cobalt for improved performance when cutting harder metals such as stainless steel or nickel alloys. Uncoated tools feature just the base substrate without any additional treatment or coatings and are suitable for a wide range of applications. 82 degree angle.

If the shanks had three flats ground on them like some of the better quality drill bits, they would be real winners.

These countersinks are the best I have ever used. I am a machinist and so I use these every day. From chamfering a hole to countersinking for a flat head bolt, these do the trick with no chatter or burrs. You do have to be careful if you are chamfering a diameter with a very heavy burr on it free hand (like plastic loves to do), you will probably end up with a lopsided chamfer. This is not the tools fault, but your own.For the professional tradesman...these are the way to go, I have tried more inexpensive styles and was greatly disapointed...break with the bucks and buy the best .

I was way more impressed with these that I would have predicted. I use them for wood working and they bore clean and precise countersunk holes (using a drill press - have not tried them with a hand drill). They produce a smoother cut and extract the debris significantly better than traditional countersink bores.

Really nice set of chamfer bits, I get no chatter marks from these as opposed to regular fluted chamfer bits. Very nice quality
